Sure. Although, it might be better to add it to the DVprofile so that
if profiles change midstream like this: A, B, A then the anchor from
A doesn't need to be reinitialized.

Anyway, attached is the new patch that tries to do exactly that. Please
keep in mind that DVtables will contain *all* dynamic tables
(work_chunks, video_place, unweight) in the future. The only bit that
I don't like about how it works is the awkward initialization sequence
in dvdata.h. If anybody has better ideas on how to separate dynamic/RW
portion from the static/const DVprofile[] -- please let me know.

Thanks,
Roman.
